Concrete pavement joint-cutting device for highway bridge construction and using method thereof

Abstract

The invention discloses a concrete pavement joint-cutting device for highway bridge construction and a using method thereof. The concrete pavement joint-cutting device comprises a supporting mechanism, wherein a support moving in the direction of the supporting mechanism is arranged on the upper surface of the supporting mechanism; a push handle is arranged on one side of the support; a movable plate sliding up and down with the support is arranged on the inner side of the support; a height adjusting mechanism is arranged between the movable plate and the support; a protective cover is connected to one side of the movable plate through a connecting plate; and a cutting disc is arranged in and rotationally connected with the protective cover. Through cooperation of a bottom plate, guide rails, limiting strips, moving wheels and annular clamping grooves, the support moves in a linear direction all the time in a moving process, so it is guaranteed that a kerf cut by the cutting disc is linear, attractiveness is improved, workers do not need to observe whether the kerf is linear or not all the time, the workers can conduct joint cutting more easily, and then the labor intensity of the workers is reduced.

Description

technical field [0001] The invention relates to the technical field of highway and bridge construction, in particular to a concrete pavement cutting device for highway and bridge construction and a use method thereof. Background technique [0002] Concrete: refers to the collective name of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering. [0003] In the construction of concrete pavement, in order to prevent the thermal expansion and contraction of the pavement due to the extreme low temperature in winter and the extreme high temperature in summer, damage the road, and reduce the service life of the pavement, the concrete...

AI Technical Summary

Problems solved by technology

[0004] However, when the existing technology cuts the seam, it is all done manually by feeling. It is difficult to straighten the seam on the road bridge concrete pavement, which seriously affects the construction quality of the seam on the road bridge concrete pavement. When cutting the seam, it is time-consuming and labor-intensive, and a large amount of smoke and dust are likely to appear during the seam cutting, which will affect the surrounding environment. In addition, the existing concrete pavement seam cutting device cannot adjust the depth of the seam, which is poor in flexibility and is not conducive to use
